A coffee estate is a coffee plantation and vise versa.
Author’s note:
There is no difference in quality between an estate and a plantation in my opinion.
Espresso is made by forcing hot water at nine to 10 bars of pressure through very finely grounded coffee beans. The extraction of espresso happens quicker than filter-drip coffee because the more finely ground coffee has a larger, wetted surface area. The high pressure hot water in an espresso machine is necessary to overcome the extra surface tension produced by the larger surface area of the finely ground coffee.
What makes espresso so different than filter drip coffee is that it has crema, a reddish brown liquid that expands as water is forced grind and out through the porta-filter forming a shot of espresso. Crema is the most important clue to the flavour of the espresso. It also provides the beauty in what is behind all that awesome latte art and gives the aftertaste of espresso coffee drinks. Because of the crema and quick extraction process, espresso has more flavour and less caffeine than filter-drip coffee.
